T0 aZZ whom it may concern.-

Be it known that I, ADOLF FRANKE, a citizen of the German Empire, and a resident of Berlin, Germany, have invented certain new and useful Improvements in Cash-Registers, (for which I have received Letters Patent in Germany, No. 86,840, dated September 19, 1894; in Switzerland, No. 11,591, dated January 17, 1896; in Belgium, No. 119,484, dated February 15, 1896, and in Italy, XXXI, 40,707, LXXX, 9, dated March 31, 1896,) of which the following is a specification.

My invention has reference to cash-registers, and has for its object to provide a check for the cash receipts by, first, giving each purchaser a printed receipt for the amount paid; secondly, by registering the same amount upon a continuous moving strip of paper, and, thirdly, by recording the total amount receipted for and giving visual indications of the same. To this end I use a writing-machine similar to a type-writer, but provided with types corresponding to the numerals from 0 to 9 only, and which by means of two properly-arranged type-wheels prints the amount of the sale upon the receipt and upon the continuous moving strip whenever the corresponding keys are depressed. lVith this type-writing machine is combined a counting or adding mechanism which adds the amounts receipted for. For the effective working of the apparatus provisions are made to permit but a very slight movement of the type-wheels when the O is printed, that they move a fixed amount when the numeral 1 is printed, twice the amount for the numeral 2, and so on, and that the rotation of the type-wheel shaft at the same time actuates the adding mechanism. The lateral motion necessary to place the numerals in succession on the paper side by side is utilized for simultaneously causing the units to be first added in the totalizer, then the tens, then the hundreds, and so on.

The nature of myinvention will best be understood when described in connection with the accompanying drawings, in which-- Figure 1 is a plan or top view of an apparatus embodying my invention. Fig. 2 is a front elevation, partly in section. Fig. 3 is an elevation from the left-hand side of Fig. 1. Fig. 4 is a section on the line 4 4, Fig. 1. Fig. 5 is an elevation taken from the right-hand side of Fig. 1. Figs. 6 to 9 are detail views.

Similar letters and figures of reference designate corresponding parts throughout the several views of the drawings.

Referring to the drawings, the letters T T designate two type-wheels affixed to the opposite ends of a continuous shaft W, mounted in bearings L, L and L permitting rotary and longitudinal motion of the same. Upon this shaft and between the bearings L and L is mounted a sleeve R, which sleeve cannot rotate upon the shaft. In said sleeve is formed a longitudinal slot S, through which projects an arm P, fixed to the shaft \V,whioh arm, in conjunction with a second arm P, affixed to the shaft, carries a raclebar Z. To the sleeve R is rigidly connected an arm P which is bifurcated at its end for the reception of the bar Z, thus preventing turning of the sleeve R on the shaft 1V, while permitting relative motion in the axial direction of said shaft.

F, Fig. 2, is a spring placed within the sleeve R, which tends to produce lateral or axial displacement of the sleeve, which is counteracted by one of the teeth of the bar Z engaging with one of two pawls M and M.

Referring to Figs. 2 and 9, the letter R designates a hub rotatively mounted on the sleeve R and carrying the fixed pawl M and the hinged pawl M. By means of a bent spring F this ring R is forced against the sleeve into such a position that one of the teeth of the bar Z rests upon the fixed pawl M. Nhen, however, the sleeve and shaft are turned, the arm on the fixed pawl strikes against a screw V, (which action takes place when the entire apparatus returns to its normal position,) the corresponding tooth of the bar Z becomes disengaged from the fixed pawl M, and by the pressure of the spring F the shaft 7, together with all the parts connected thereto, is thrown to the left, so that the next following tooth on the oar Z bears against the movable pawl M. As soon as the shaft Consequently every time a numeral is printed the shaft IV, together with the type-wheels T and T, is shifted a predetermined distance to the left. To turn the shaft IV through an angle corresponding to the required number, a

toothed wheel Z and a starwheel X are provided and rigidly attached to the sleeve R. A toothed segment Z turning on the spindle O, engages the toothed wheel Z. The point of a hook X is adapted to engage with the several teeth of the star-wheel X, said hook turning on the same axle as the toothed segment and being adapted to arrest the rotation of the type-wheels at a fixed point. The teeth of the star-wheel X are so cut that every time one of the types of the type-wheel comes opposite the paper and ink strip one of the teeth of said star-wheel is engaged by the hook X. The ten types are distributed over a semicircle, so that the angle between any two succeeding types is always one-twentieth of the whole circumference.

The keys, which may be of any usual construction, rest upon levers II, which when depressed carry along the bar Q and thehook X, rigidly connected thereto. The levers II are also provided with screws U, adapted to press upon the rail Q, so as to cause it and its arm B to participate in the rotary movement. The arm B advances the toothed segment Z through the medium of a spring. The bar Q is so arranged that when any one key is depressed it participates at once in the en tire movement of the lever II belonging to the particular key. The rail Q participates in the movements of said lever only when the key 9 is depressed, while when the remaining keys are depressed it is not moved until after the bar Q has traveled through a predetermined distance, this being due to the difference in length of the several screws U. lVhen key 9 is depressed, the toothed segment Z and the hook X are set sim ultaneously into motion and turn the shaft IV through such a distance that the hook X engages the last tooth of the star-wheel X. On the depression of another key the hook X travels through the same distance, but the toothed segment Z travels through a shorter distance, in consequence of which the shaft IV will be turned proportionately less and the hook X will engage aprevious tooth. I11 this manner each depression of a key turns the shaft axially far enough to place the type corresponding to the key exactly opposite to the paper. The elasticity of the spring connecting the arm I3 to the toothed segment Z permits a continued downward motion of the key after the motion of the type-wheel shaft has been arrested, and by this continued mo tion two hammers G and C, likewise rigidly connected to the bar Q, are raised sufficiently to strike the paper strips and the interposed ink-ribbon and to move the same against the type, thereby effecting the printing. After the depression of the keys all the parts are 'returned to their normal positions through the agency of the springs and the shaft W moves to the left, as previously described.

In the drawings I have not shown the parts in their normal positions, but show the keys q partly depressed, so that the tooth of the rod Z rests upon the fixed pawl and the typewhecls are turned sufficiently to bring the type 1 about opposite to the paper.

I shall now proceed to describe the construction of the adding mechanism, which is placed between the bearings L and L and is shown in detail in Figs. 6, 7, and S. This adding mechanism consists of a number of numeral-wheels .2, upon the peripheries of which are placed the numerals O to 9, the same being engraved twice in their natural sequence. Rigidly connected to the hub of each numeral-wheel and turning on the shaft IV is a ratchet-wheel 5, provided with twenty teeth, and within the space between the numeral-wheels, Fig. '7, are placed eccentrics c. Adjoining each ratchet-wheel s is rotatively mounted upon the same shaft IV a cam g of peculiar form. Each ratchet-wheel is engaged by three pawls, of which the first pawl a has a fixed pivot 0, while the second pawl Z) is secured to the respective cam g, and the third pawl c is placed on an arm (1 likewise turning on the pivot o. On the rod Z are hooks 7L, adapted to engage projections on the cams g. IVhen the shaft W is moved to the left of its normal position and the pawls M M slide from one tooth to another, the hooks it also move sufficiently to the left to liberate one of the cams g and engage with the next succeeding arm. That arm (Z just in contact with the respective hook it must share in the rotation of the shaft IV, and consequently on the depression or release of a key is turned forward and back as many one-twentieths of the periphery as correspond to the number of this key.

In Fig. (3 I have shown the system in its normal position, while in Fig. 8 the cam g is shown in engagement with the hook h and turned through a fixed distance by the same. During the forward movement of the cam g the corresponding ratchet-wheel 3, together with the numeralavheel, remains stationary, because it is held by the fixed pawl. On the return movement the pawl Z) pushes the ratchet-wheel back to the corresponding number of teeth. As soon as one of the numeralwheels falls back from 9 to O the numeral wheel corresponding to the next higher decimal is moved forward one unit by the pawl c. On the arm (Z is formed a nose 7t, which with its widened part projects into the depression of one numeral-wheel and is adapted to be lifted by the eccentric c of the adjoining numeral-wheel. lVhen this adjoining numeralwheel-that is, the one which corresponds to the next lower decimalstands at 9 the nose is exactly upon the projection of the eecentric. hen the adjoining wheel moves from 9 to O, the nose slides down on the eccentrio, the arm (Z is pressed in by the flat spring shown in Fig. 3, and the pawl c advances the wheel through one tooth. The pawl 0 also serves to hold the toothed wheel fast and to prevent it going too far by its momentum. Upon the ratchet-wheel sis located a stop 1), which prevents the tooth from being turned farther out than shown in the figure. It also serves to prevent the ratchet-wheel from being moved forward when the arm d is in the position shown in Fig. 6, and consequently the ratchet-wheels in general are prevented from moving forward or backward. IVhen the arm d is moved into the position shown in Fig. 8, the pawl c liberates the ratchet-wheel. Now in order that the individual arm 61 by which the ratchet-wheel is to be turned should be sufficiently thrown out an eccentricshaped projection is formed on the cam g, and which is likewise actuated by the nose 7.; and moved outwardly as soon as the cam g is turned. In printing a number the units are thus first printed, and the numeral-disk at the extreme right corresponding to the units participates in the rotary motion, so as to increase the record of the counter by the corresponding amount. Then the shaft IV moves one space to the left, and whereupon a second key is depressed. The second numeral corresponding thereto appears upon the strip as a ten. At the same time the second tens-wheel shares in the rotary motion, disc.

Type-wheel T serves for printing the receipts, while the type-wheel T prints the amounts upon a continuous paper strip in close succession. The receipts are likewise printed upon a continuous strip of paper, which after each imprint is fed forward a certain distance and then out. After a number has been completely printed the lever E (shown in Figs. 1, 2, and 5) is pushed forward and thereby turns the levers E and E affixed to the same shaft. The paper strip is thereby pushed forward by the lever E moving the carriage N forward by means of the links K, while the latter by means of an intermediate piece feeds the paper upon the table 3 The nose E of the lever E then closes the shear or cutters (shown in Figs. 2 and 5) and effects the severing of the paper. The arms E carry a die, which when depressed is turned and strikes against the paper and prints a suitable heading. The lever E also engages the lever G, and thereby turns the shaft G whereby, in a manner readily to be understood from the drawings, the ink-strip T is fed forward through a predetermined distance on its rollers G and G bringing forward a fresh piece beneath the two type-wheels and turning the roll W through a corresponding distance and feeding forward the paper strip beneath the type-wheel T. Simultaneously with the levers E an d E a short lever B is turned, which pushes the lever B backward and draws upon the lever 13 The latter grips the pin 8 and pushes the shaft WV back to its original position, so that the tooth farthest to the left on the rack-bar Z lies against the movable pawl M. After the lovers E, E, and E have again been raised all the parts are in their normal positions and the apparatus is in condition for printing another receipt.

What I claim as new is 1. In a cash-register, the combination of a shaft mounted to turn and to move longitudinally, a numeral-segment mounted on said shaft, means for turning said shaft and for moving the same longitudinally to bring the respective numeral into the printing-line and to place the numerals side by side on the strip beginning with the units, and a counter or totalizer operated by the movements of the shaft, substantially as described.

2. In a cash-register, the combination of a shaft mounted to turn and to move longitudinally, means for turning said shaft and for moving the same longitudinally, a counter or totalizer composed of a series of numeraldisks placed side by side, and operative connections between said shaft and said numeraldisks for operating the latter to add the individual amounts, substantially as described.

8. In a cash-register, the combination of a shaft mounted to reciprocate and to move longitudinally, a numeral-segment attached to said shaft, a series of keys, and operative connections between said keys and the shaft for turning the same and for moving the same longitudinally to bring the respective numeral into the printing-line and to place the numerals side by side on the strip, substantially as described.

4. In a cash-register, the combination of a shaft mounted to turn and to move longitudinally, a numeral-segment mounted on said shaft, a record-segment mounted on the same shaft, means for turning said shaft and for moving the same longitudinally to bring the respective numeral into the printing-line and to place the numerals side by side on the strip beginning with the units, and a counter or totalizer operated by the movements of the shaft, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 4th day of January, 1896.
